FriendsInSpace well I didn't want the Marker to be out of reach or exorbitant, and I didn't want it to compete against the free market either. The goal is for it to be more expensive than players - but worth it if you'd rather not buy from someone you absolutely hate lol
If there were more players/market transactions, then I could make an algorithm to run it dynamically. If I did it now then I think it would be too susceptible to manipulation, so manual adjustments once in a while are fine.
